Research on access control conflict detection for Intelligent City Information System Han Sanga in the background of Intelligent city, the information system needs resources sharing and cooperative operation, and the traditional access control technology faces new demands and challenges. Based on the RBAC model, this paper introduces the element of "application", which includes different roles and permissions, and realizes the unified authorization by giving the people the roles that belong to different applications. At the same time, the model constraint and model parameter configuration as well as the corresponding conflict detection strategy are proposed for the new model, by detecting the basic operation of tree elements, the Role association permissions ...

Research on access control of management information system based on cloud computing Chongqing in this paper, the existing workflow technology and access control model are fully studied, based on the TRBAC model of the most suitable workflow management system, some improvements are made to the model from the angle of application. This model introduces the role concept of role-based access control into task-based access control, the core idea of which is to enable the user to access the data by acquiring a role (but the authorization step that contains the permission must be activated, otherwise the role's permissions will be frozen). ...

Mobile cloud service access control with privacy protection Jing Po Bai Guangwei Cade Zhang Yi for security and privacy protection issues in mobile cloud services, a mechanism for anonymous use of cloud storage services is proposed. In the Anonymous Identity Registration section, the 0 Knowledge verification and digital signature technology simplifies the key verification step of mobile cloud users, while the third party uses the user to bind with own ID card to prevent users from malicious use of mobile cloud services; In the data Sharing section, the system extracts the shared account parameters, Used to troubleshoot data security degradation caused by shared key loss. Combined with the method of theoretical analysis ...

Research on data access control method in cloud computing Nanjing University of Posts and telecommunications This paper proposes an attribute-based access control model (DACC) for cloud computing environment using CP-ABE encryption algorithm. The core idea is to use the AES symmetric encryption algorithm and the Cp-abe encryption algorithm, respectively to encrypt the data and symmetric key, and the user of the attribute matching to decrypt the key cipher text and the data cipher in sequence. In order to reduce the cost of storing and updating keys, the Key Distribution center KDC is introduced to manage attributes and keys. Cloud computing Service Provider ...

Research and realization of access control subsystem based on attribute encryption in cloud storage Sun Youpeng because of the complexity of the cloud environment, the various entities are not trusted, so password access control technology to prevent user data leakage is the most direct means. In recent years, the academia has introduced the attribute-based encryption system in the access control, which is a method developed on the basis of identity encryption.
